Membrane-free selective oxidation of thioethers with water over a nickel phosphide nanocube electrode

Cell Reports Physical Science, Год журнала: 2021, Номер 2(6), С. 100462 - 100462

Опубликована: Июнь 1, 2021

Summary Developing a membrane-free oxidation reaction, especially using water as the oxygen source, to generate high-value chemicals with high selectivity for replacing low-value O2 over cost-effective catalyst is significant. In this study, nickel phosphide (Ni2P) hollow nanocubes are designed and shown enable selective of thioethers sulfoxides sulfones H2O. situ Raman data reveal surface reconstruction Ni2P NiOOH, resulting NiII/NiIII redox couple promotes transformation. The 18O-labeling experiments confirm H2O source. A cross-coupling sulfur-related radical hydroxyl proposed. Sulfoxides yields can be controlled via potential modulation, which challenging traditional methods. Deuterated readily synthesized one-pot thioether tandem H/D exchange processes. Wide substrate scopes, good functional group compatibilities, integrating hydrogen production, paired synthesis deuterated sulfoxide arene highlight strategy.

Advanced Synthesis & Catalysis, Год журнала: 2023, Номер 365(13), С. 2248 - 2254

Опубликована: Май 27, 2023

Abstract Herein, an eco‐friendly and atom‐economical electrochemical methodology with isatins 1,2,3,4‐tetrahydroisoquinolines through NHPI/O 2 ‐mediated intermolecular oxidation/annulation is disclosed, leading to a variety of polycyclic quinazolinones in 46–82% yields. This oxidative cyclization proceeded transition metal‐ strong oxidant‐free conditions generated H CO as byproducts. Additionally, late‐stage functionalization broad substrate scope demonstrated the synthetic usefulness this protocol.

Electrochemical Heteroatom‐Heteroatom Bond Construction

The Chemical Record, Год журнала: 2021, Номер 22(1)

Опубликована: Авг. 31, 2021

Heteroatom-heteroatom linkage, with S-S bond as a presentative motif, served crucial role in biochemicals, pharmaceuticals, pesticides, and material sciences. Thus, preparation of the privileged scaffold has always been attracting tremendous attention from synthetic community. However, classic protocols suffered several drawbacks, such toxic unstable agents, poor functional group tolerance, multiple steps, explosive oxidizing regents well transitional metal catalysts. Electrochemical organic synthesis exhibited promising alternative to traditional chemical reaction due sustainable electricity can be employed traceless redox agents. Hence, oxidants and/or metals could discarded under mild high efficiency. In this context, series electrochemical approaches for construction heteroatom-heteroatom were reviewed. Notably, most cases illustrated dehydrogenative feature clean energy molecules hydrogen sole by-product.
